Iíve gone through a couple sets of dome lift motors and lift arms.
I agree that the design is faulty, but the replacement lift motors last me a couple of years and the price isn't too high.
However, there's a relatively easy "fix" you might want to try that does seem to extend the life of the motor. Take a small block of wood and attach it to the side of the fan "opening" so it is just below the rotating lift knob when it is pushed up into the proper position.
Essentially, what the block is doing is preventing the knob from being pulled down to the Manual position. For me this has extended the usable life of the motor for a couple of years. Eventually, though, I have to break down and buy a new one.
This is the one I buy. It's an exact replacement for mine, screw holes line up properly. https://smile.amazon.com/Atwood-K605...gateway&sr=8-1
